TOTO's Photocatalyst and related patents
HYDROTECT Partners extending aroud the world
We are working on applications for patents and the acquisition of the technical rights that cover a broad range of areas from the basic invention to the applied use of photocatalyst technology in order to protect the intellectual rights concerning photocatalyst technology.
In addition to the basic invention of photoinduced super-hydrophilic technology, we have filed more than 1,300 domestic and overseas patent applications in relation to applied products, manufacturing technology and coating materials, and have been granted approximately 370 worldwide patents to date. We have also signed license agreements with 100 manufacturers (including 19 overseas manufacturers) across a wide range of sectors, mainly in Japan, North America and Europe.
